What is a Gravity Gold Recovery Circuit?
We've got our cyclone for size separation, and then we've got our gravity circuit. The placement of the gravity circuit can either be on cyclone feed or here on cyclone underflow – I'd say this has been the traditional location in the underflow. And I'd say this is more of the modern location for the gravity circuit.

Explainer: How to develop a gold mine – from exploration
Construction generally takes a few years, depending on the mine location, the size of the development and the regulations in the relevant region. An open pit (or surface) mine is used when the ore body is up to a depth of approximately 400m. Otherwise an underground mine will be built, while some mines are a hybrid open pit/underground mine.
